Nor can we, which is why we thought it would be fun to make some suggestions to Reynolds and other single celebrities, about who they should date in the coming year. We enlisted the help of Match.com's relationship expert, Whitney Casey, author of "The Man Plan: Drive Men Wild -- Not Away."

Casey's advice to all celebrities and us mere mortals: "Be cognizant about the time they spend making moments together. Once you become one with someone else, you can't continue being that celebrity you were."

Casey believes Reynolds and Johansson, who announced Tuesday that they were ending their two-year marriage, fell victim to spending more time apart than together, "sharing memories rather than making memories." She said a good rule of thumb for all couples is: 30 percent of the time should be spent pursuing individual goals, friends and work and 70 percent should be spent together.

"Here we can use Brad (Pitt) and Angelina (Jolie) for something good," she said. "They are way busier, yet they manage to keep a healthy relationship. They set apart their schedules to be together or they shoot in the same locations."

If two of the biggest stars on the planet can make it work, then there's hope for other star couples. Here are our suggestions for potential matchups in 2011:

Jenny McCarthy and Charlie Sheen

The two met again recently on the set of "Two and a Half Men," where McCarthy reprised her role as crazy Courtney. Though Sheen's character breaks up with her on Monday's episode, there was clearly chemistry between the two.

"In person, you can see why people dig him," McCarthy told the ladies of ABC's "The View" on Wednesday. "He does exude this sexual energy."

And wouldn't you know it -- both McCarthy and Sheen are single again. Sheen filed for divorce from wife Brooke Mueller in November. McCarthy recently broke up with Vegas performer Jason Toohey, whom she began dating after her five-year relationship with Jim Carrey ended in April.

Being single for the second time this year seems to have caught McCarthy off guard. "I'm not like a serial dater," she told "The View" co-hosts. "I go into a relationship for several years. This is the first time since I was 12 that I'm single. I'm being picky now."

Too picky for Sheen, who has a history of alcohol and drug abuse, hiring prostitutes and domestic assault? McCarthy was undaunted by Sheen's latest flap, in which he was reportedly found drunk and naked in a New York City hotel room, though it occurred just before the "Two and a Half Men" taping.

"He was great," she said. "He was super cool."

Then again, McCarthy admitted she brings out the best in people she's around. "I feel like I'm a cocker spaniel on set," she said.

McCarthy could be exactly what Sheen needs -- someone to calm him down. A former Playboy Playmate, she certainly fits his type. And the two could bond over the travails of parenthood.
